Calculator Based Laboratory-Data Collector

Six channels for data collection: Measure motion, temperature, light, pH, force and more (with the appropriate probes) Connects to TI-85 (2249A01) Three modes of operation: Communications (for normal data collection), Multimeter (measuring voltage, resistance, etc. as a stand alone device) and Internal (for measuring internal battery voltage) Screen displays CBL status and collected data Trigger manually starts data collection from CBL unit CH VIEW (Channel View): allows monitoring of data being collected on active channels Input/output port for connecting to 2249A01 Calculator After TI-85 (2249A01) sets up the CBL, the CBL can be disconnected to stand alone as a data-collection device. Once data is collected, CBL can be reconnected to the calculator to retrieve and analyze data. Comes with 3 probes: temperature, light and voltage. Impact-resistant carrying and storage case provided. Comprehensive guidebook and a workbook of classroom experiments for physics, math and chemistry included. Unit is lightweight, hand held and battery operated (4 “AA” batteries included). Free videotape available: Calculator Based Laboratory System; demonstrates classroom use of the CBL with a graphing calculator.
